True or False: Nosocomial infection is another term for a hospital-acquired infection.

In 2020, as the number of cases of COVID-19 increased and spread across the world, it became considered:

When initially researching a nosocomial outbreak, epidemiologists should record which of the following:

Pathogen is defined as:

True of False: All microbes cause disease.

This non-living infectious agent, which causes the flu, cannot replicate on its own & infects healthy cells as hosts.

This living infectious agent, also known as worms, is acquired through consumption of contaminated food or water and often causes rapid weight loss.

This non-living infectious protein causes normal brain proteins to fold abnormally, leading to neurological symptoms (confusion, hallucinations).

This living, animal-like infectious agent thrives in the digestive tract of a host, depriving the host of nutrients from food and can sometimes be treated with antiprotozoal medication.

This common living infectious agent, which cause tuberculosis (TB), can be acquired in a variety of ways and can be treated with antibiotics.

This living, multicellular infectious agent, which causes athlete's foot, includes mildews, molds, and mushrooms.

An infected individual hugs an uninfected individual, depositing the pathogen on the new person. This form of disease transmission is an example of:

An infected individual pays at the grocery store with infected cash, spreading the pathogen to the cashier. This form of disease transmission is an example of:

West Nile Virus is spread through in intermediate insect that carries the pathogen: mosquitos. This form of disease transmission is an example of:

An infected individual coughs into the air, then an uninfected individual inhales the particles, acquiring the pathogen. This form of disease transmission is an example of:

The infectious dose of Ebola is 1-10 viruses, whereas Influenza A requires more than 790 viruses to infect a new host. Which of these viruses are considered more infectious?

When infectious pathogens enters the body, white blood cells (B-cells), produce THESE molecules to attack or impair the pathogens:

Vaccinations are an example of:

These components of our innate, or nonspecific, immune system are found in our nose, trachea, and lungs and work with mucus to trap foreign invaders:

These components of our innate, or nonspecific, immune system are found in digestive tract and on our skin to prevent foreign invaders from attaching.

What part of the chain is seen in this photo?

What comes next in the chain of infection? Agent, reservoir, portal of exit,_________.

Herd immunity protects people whose immune system is weak.

People with cancer can be vaccinated.

There are two ways to create "Herd Immunity" they are:

Natural Immunity occurs when . . .

The herd immunity threshold was calculated to be 75%. What does this mean?

The R0 for a new virus was measured to be 3.5. How infectious is this new virus?

Which disease is more dangerous?

A molecule that the immune system recognizes either as part of the body or as coming from outside the body:

Which of the following is a way to spread infectious diseases?

What is the molecule located on the outside of a pathogen that the immune system recognizes?

What attaches to antigens and tags the pathogen for destruction?

The diagram shows a pathogen, what is the arrow pointing to on the surface of the pathogen?

What is a preparation of dead or weakened pathogens that is introduced into the body to cause an immune response?

What function do memory cells have in our body?

Which of the following statements is NOT true about antigens?

What type of cell kills infected cells?

What type of cell creates antibodies?
